"I highly recommend Sparks Electric. They recently completed an electrical box expansion, installed two ceiling fans, and replaced two bathroom fans in my home. Blake provided an itemized quote for a fair price before starting the job. His team arrived on time, were polite, and cleaned up after themselves. They also had excellent communication throughout the project. Iâ m very pleased with their work and recommend them to anyone looking for electrical work."

"The furnace took 4 days to get approved( not counting a Sunday) the others were quick but the water heater had to be ordered so without hot water for a week. One ceiling fan was easy but within a year their policy changed and They would not install the one I purchased and had to get a new one approved and then ordered online and took several weeks to get straightened out. Not sure who was at fault, AHS, installer or scheduling with renter. Fee is usually $75 per visit"

Bathroom Fan Installation questions, answered by experts

A whole-house fan will not allow you to control your home's temperature and keep it at a specific temperature like a traditional AC unit would. You rely on the night and morning weather to cool your home down efficiently. Also, whole-house fans can be loud and may allow cold air to enter your home in the winter. They also require penetrations through your exterior walls or roof, which could invite water and pests in if they aren’t installed properly.

Once you remove all standing water and puddling, you should run fans for 24 to 48 hours to remove the remaining moisture. For severe water damage, it’s a good idea to run them for three to four days to be safe. Make sure you buy or rent the proper size and number of fans for your water-damaged area.

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

Whole-house fans cost significantly less to run than a window AC unit. You'll pay an average of $0.01 and $0.05 per hour to run a whole-house fan compared to $0.06 to $0.88 per hour for the cost to run a window AC, depending on its size and the size of your home. They also use far less electricity than traditional central AC units.

Ceiling fans offer multiple benefits for your home. They improve air circulation to prevent stagnant environments and provide cost-effective temperature control, which can reduce reliance on your HVAC system and help lower utility bills. In addition to their functional advantages, ceiling fans can also enhance a room's aesthetic appeal with features like built-in lighting and modern styling.
